近日，据有关媒体报道，日本警察厅对富士山火山再次喷发一事采取了应对措施。同时，为防止富士山火山喷发，日本警察厅目前正为各级警察发放防尘口罩。近年来，日本有关富士山火山喷发的消息层出不穷，如果这一次富士山真的喷发，会有什么影响呢？
Day X has arrived.
Mount Fuji, Japan's most famous volcano, is erupting for the first time in 300 years.
It's raining ash, lava and toxic gases down on the world's largest city.
What would be like to witness this epic eruption?
How much ash would cover Tokyo like a dark gray blanket?
This is WHAT IF and here is what would happen if Mount Fuji exploded tomorrow. Mt. Fuji is located only 100 kilometers from Tokyo, where 37 million people live.
But this tall, cone-shaped giant isn't just any mountain.
It's a stratovolcano.
The last time Mt. Fuji erupted was over 300 years ago.
When it blew up back in 1707, it blanketed the city in ash.
